Transcript for 3 adult bald eagles watch over 3 eaglets in nest along Mississippi River
And to a different kind of modern family. Tonight, along the Mississippi river, near Fulton, Illinois, an extremely rare sight. Three adult bald eagles, two male, named valor I and valor I, and one female, Starr, sharing baby duty. Co-parenting three eaglets who had just hatched with the world watching. Every moment of this livestream run by the stewards of the upper Mississippi river refuge. Here in early March, each taking turns keeping the eggs warm. One flying away, the other studying the eggs. The eggs hatching. The proud parents taking turns feeding their young. Watch on the right, one parent feeding a baby, while the other flies in with a fish. That nest is ten feet deep, six feet across. The eaglets will likely leave the nest in two months. Here they are, just days old. Then last week. And here they are just today. Wow. They'll soon be off to college. Thanks for watching here on a Wednesday night. I'm David Muir. I hope to see you right back here tomorrow night.
